Apply Pythagoras:
length = sqrt( (10--4)² + (6-3)² ) = sqrt(205)

Answer:
A is the answer
Step-by-step explanation:
Answer:
Name a transversal - i
Name all corresponding angles -
6 = 8
1 = 3
2 = 4
5 = 7
Name all alternate exterior angles -
1 = 5
4 = 8
In order to calculate the total cost of the purchase, we must first assess that there were two items bought, turkey and lamb. Next, we see multiply the cost of the first item by its quantity, so:
cost(T) = 2.15 * 7.89
cost(T) = $16.96
And repeat for the second item:
cost(L) = 1.87 * 7.89
cost (L) = $14.75
Finally, the total cost is the sum of these costs. So
Total = 16.96 + 14.75
Total = $31.71
